SOUND-REPRODUCING INSTRUMEN T.

Specification of Letters Patent.'

Patented July 4, 1911.

Application filed August 19, 1910. Serial No. 578,016.

Be it known that I, ROBERT WV. VVEATHER- at Selmore, in the county ofChristian, State of Missouri, have invented certain new and useful Improvements in Sound-Reproducing Instruments; and I do hereby declare the following to be a full, clear, and "exact dc "scription of the invention,-such as will enable others skilled in, the art to which it appertains to make and use the same.

This invention relates to sound reproduc- .ing instruments and has special reference to a mechanism used in connection with machines of the cylinder type to replace the stylus of the reproducer at the beginning of the record after the same has been played.

The principal object of the invention is to improve and simplify the general construction of devices of this character.

A second object of the invention is to provide a means of novelcharacter 'for stopping the machine after the stylus has been move back to the starting point.

A thirdobject of the invention is to pro ride-a novel form of holder for the reproduccr especially adapted to be used with an and specifically set forth in the claims.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and :.Figure 1 is a plan view of a phonograph constructed and equipped in accordance with this invention. Fig. 2 is a rear elevation thereof. Fig. 3 is a section on the line 3-3 of Fig. 1. Fig.

. 4 is a section on the line 4-4; of Fig. 1.

Fig. 5 is a detail view of a certain throw ofidevice used inconnectioii with this instrument. Fig. 6 is a partial section on the line 66. of Fig. 1. v

The numeral 10 indicates a portion of the shown as it forms no specific part of the The casing 1s provided with the invention. usual top 11 whereto is attached a base plate 12. Secured to the base plate adjacent one end 15 a pair of spaced standards 13 the space between the standards being closed in on the top and sides by a cover 1-1. The space thus lnclosed forms the gear box for the devlce. Journaled in the standards 13 is a shaft 15 on one end of which is a belt. wheel 16 over which runs the belt 17, this.

belt passing downward into the casing 10 and being driven by a suitable pulley on the motor in the usual manner. The other end of the shaft 15 is provided with the usual mandrel 18 whereon may be held the cylindrical record 19. Secured to the base 12 is a bearing block 20 whereto is pivoted the lower end of an arm 21 provided with a centering projection 22 which engages in an opening in the end of the mandrel to hold the same in proper position while the machine is in operation. in either the raised or lowered position by a suitable spring 23. Fixed to one of the standards 13 and extending out in parallel relation to the shaft 15 is a rod 24. The outer end of this rod 24 is secured to an arm 25which projects fronr a standard 26 firmly fixed to the base 12. Slidable on the rod 24 is a sleeve 27 comprising a pair of spaced sections which are connected together by a yoke 28 extend ing backward from the adjacent ends of the sections. Extendingforward from the ends of the yoke arms is a pair of spaced arms 29 between, which is pivoted the reproducer arm 30 carrying on its forward-end a ring 33 wherein is held a reproducer 34. Fixed to the bight of the yoke 28 isa screw 35 which passes through the rear end of the reproducer arm. At the rear of the ring 33 there is provided a second screw 36 which is firmly fixed to the ring. Held upon the This arm 21 is held.

screws 35 and 36 is a locking bar 37 having a forked end 38, the arms of the fork being provided with downwardly turned extremi= ties 39 which bear against ,the top of the reproducer. The screw 35- carries a thumb nut 40 which serves to adjust the position.

of the reproducer with reference to the yoke and also to hold the rear end of the arm 37. On the screw 36 is a thumb nut 41 which serves to hold the front end of the arm- 37 insuchmanner that the projections 39 bear firmly on the reproducer when the latter is in position. Extending from what may be termed the inner standard 13 to the standard a trainof gears 43.

' ward and rearward from the yoke 28.

, to engage the screw forward extremity of 44 is a coil spring 48.

26 is a feed screw 42 of the ordinary type employed in machines of this character and this feed screw is geared to the shaft 15 by Extending rearwardly beneath the shaft 42 is an arm 44 which is preferably integral with and projects downthe upper side of this arm 44 there is provided a segmental nut 45 which is adapted the arm is raised. I producer and parts The weight of the reforward of the rod 24 is such that the normal tendencyof the rear end of the arm 44 is to lift and hold the nut in position on the'screw.

At 46 is a forked lug between the arms of which is pivoted a lever 47. Between the screw 49. In order to hold the lug out of engagement with said screw during. the progress of the segmental nut 45 along the screw 42 the arm 47 has pivoted thereto a latch 51, the upper end of which projects through an opening 52 formed .in the rear end of the arm 44 and this'latch is provided with a notch 53 which is adapted to engage the edge of the opening 52 so that the rear ends of the arms 44 and 47 may be held apart against the action of the spring 48.

Projecting rearwardly from the standard 26 is an arm 54 wherethrough extends a thumb screw'55 the extremity of which-lies in the path of the upper end of the latch 51. This thumb screw has surrounding its stem between its head and the arm 54 a spring 56 which acts as a lock spring to revent accidental movement of said screw.

ow, in the operation ofthis portion of the device when the machine is started the reroducer will travel toward the left of Fig. 2 until the latch strikes the screw 55. When the latch :thus strikes said screw the notch will be released from its engagement with the arm 44 and the spring 48 will force thearm 47 upward at its rear end until the lug 50 contacts with thescrew 49. The arrangement. of the parts is such that the spring 48 is of sufiicient strength to conthis movement by forcing the rear end and thus releasing thenut 45 from the screw 42. This will 42'when the rear end of.

this lever and the armcause the stylus of the reproducer to rise from the record and the screw 49 will move said reproducer rapidly toward the-right.

In order to stop the machine when the reproducer has been returned to the starting point there is, provided a switch 57- which controls the current to the motor.

This

switch is connected by a link 58 with a lever j 59 pivoted to a lug 60 mounted on theinn'er', of this lever 61 which projects standard 13. The other end lies in the path of an arm from the arm 47, the lever end lying in said path when said arm 47 is raised to engage. the screw 49. The arrangement is such that as the reproducer is moved back to the startingpoint by the screw 49 the engagement of the arm 61 and lever 59will open the switch.

so-that the latter can stop.

' sired to restart the lnstrument the arm 47 is 57 and thus throw the current ofi the motor 3 When it is de- I depressed by. means of the latch 51 and the; latter engaged with the arm 44as previously started. Upon arriving at the end of'. its travel the 'latch will bedis'engaged, thereguide rod, a sleeve mounted on said 'guide" actuate said. feed rod, a feed screw, means to screw, an arm projecting fromsaldslcev'e nut-carried by said arm and adapted toengage said feedscrew, a second armpivote'd one end of saidsecond arm, a returnscrew geared to said feed screw and adapted to engage said lug, releasable-latch means to hold the lug carrying endof the second arm away said latch when the sleeve has moved to-a constantly urging the lug fcarrying end of the second arm toward the first arm.
